I recently replaced my stock cassette player ( D1 ) with a new Alpine unit. After much trial and tribulation, and several blown fuses, I have audio from the speakers. I also have a significant amount of alternator noise. I've tried re-grounding the head unit to several different points, as well as using a noise isolator on the head unit - no improvement. All the car audio stores I've stopped in tell me to just take out the entire system and replace the factory speakers, amp, etc. I have enough other noise (roof rack, M/Ts) that I'm not looking for high-end sound... but a lack of alternator noise would be nice!
Anyone have any experience with these stereos (factory amplified system) and grounding? My understanding is that the factory system uses a "common ground" for the speakers - could this be a significant factor? If so, how and why?
Getting the factory subwoofers to work again will be the next question - but one thing at a time...
